摘要：
We propose a scheme to preserve quantum correlations in a dissipative superconducting qubit system, which consists of two noninteracting dissipative superconducting flux qubits, each driven by a time-dependent magnetic field. We investigate the influence of the initial states and the time-dependent magnetic fields on the dynamics of quantum correlations between the two flux qubits. It is shown that the quantum correlations between the two qubits can be improved in the Markovian regime and well preserved in the non-Markovian regime by applying the time-dependent magnetic fields.
